The older sister who moved in next door. The moment I saw her, I was shocked—her massive breasts were obvious even through her clothes. No, they were beyond massive—absolute monsters! Just how big were they? Using helping her move as an excuse, I made my way into her room. I couldn't take my eyes off her cleavage, her breasts nearly spilling out. I'd reached my limit. Finally, I blurted out, "Let me touch your breasts!" I dove onto her huge P-cup tits, groping them, squeezing them, lost in pure bliss. Watching them bounce wildly as she rode me in the cowgirl position, I erupted with a massive cumshot!
